First time I saw a guy ejaculate in person, I wasn't super impressed. But when I was 21 and jerked off with a friend for the first time where it was mutual masturbation and we were very much jerking off to each other jerking off, watching him cum was one of the most beautiful sights I'd seen up until that point. Not even so much him ejaculating, since we both did it into tissues but watching his face try not to react too much but still seeing the tell-tale signs of orgasmic joy was delightful.
Since I was diagnosed with an Enlarged Prostate several years ago, I have been prescribed two different drugs. One of the side effects has been that my ejaculation has been clear and thinner in consistency than before EP. I still have several videos of my cumshots on an old camera, and it helps when I watch them while masturbating. I also get off watching cumshots on porn videos. I frequently have a series of mini brain orgasms while watching them.
